Well, the MIPS compilers do some interprocedural register allocation.
HP has also done experiments with a system to keep globals in registers
across calls.  The HP work is described in the most recent Proceedings
of the Conference on Programming Language Design and Implementation.

These tricks are all pretty difficult in the presence of seperate
compilation, and the successful solutions will have to solve the
problem.
